This project aims to develop processes that can successfully functionalise the inner surfaces of high surface area to volume structures with interconnected porosity. These structures underpin many processes in modern manufacturing. Examples include columns and fluidised beds for purification, materials for energy storage and conversion, biomedical scaffolds and structures for high sensitivity sensing. The efficacy of these materials is strongly affected by the condition of the surfaces, but modifying the surfaces of internal pores deep within such structures presents major challenges. This project will provide environmental friendly, dry plasma processes to tailor surface functionality, improving the efficacy of existing processes and opening up new far reaching applications for such materials.Read moreRead less
Luminescence-based imaging system for industrial tandem solar cells. This project aims to develop an Australian-made inspection system for next-generation solar cells. Besides allowing, for the first time, fast measurements of large-size tandem solar cells, the system will also enable the determination of key parameters that cannot be measured by current methods. This capability is expected to generate new knowledge in the areas of perovskite and tandem solar cells.

Summary
Nervous tissue stimulation using Multi-Junction Silicon Photodiodes. Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices.

Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices. This project aims to develop a silicon multi-junction photodiode that can provide a photovoltage high enough to efficiently excite nervous tissue. A BMI based on this approach could be much smaller and could be powered optically via thin fibres, thus in the long run enabling smaller and safer implants for restoring function in disabled people.Read moreRead less

There has been a rapid growth in space exploration and experimentation fuelled by global support. Space hardware needs to be powered by a sustainable source of energy. The use of solar photovoltaics is the preferred choice. As we move into the era of 'commercial space', cost will become paramount necessitating the development of new cost effective photovoltaic technologies. Metal halide perovskite solar cells show the greatest potential. They have a higher power to weight ratio and are significantly cheaper to be manufactured compared to incumbent space cells.

This project aims to develop a new defect-control approach for silicon-germanium heteroepitaxial semiconductor systems to provide a route for high-throughput, low-cost, high-efficiency silicon tandem solar cells. Mismatched heteroepitaxy of semiconductors is of considerable interest for fabricating novel devices. However, the use of highly-mismatched heteroepitaxial semiconductors has been limited due to the high densities of crystal defects which degrade the performance of both majority and minority carrier devices. This project aims to develop a new defect-control approach for heteroepitaxial semiconductors by continuous wavelength diode laser processing. With heteroepitaxial silicon-germanium as an example, the project will investigate the mechanism underlying defect-cleaning, optimised designs for best performance, and designs for high-efficiency tandem solar cells.Read moreRead less
